Smart Selection tools allow you to select faces and edges of your 3D solids based on particular geometric and topologic criteria - such as length, area, and smoothness.

3D Constraints can be added to faces and edges of 3D solids to align and resize them, and will make your 3D part parametric. Many geometric 3D constraints like parallel/perpendicular, coaxial, tangent can be applied automatically using Design Intent recognition.

NOTE

BricsCAD is a history-free modeler; it does not create parent-child dependencies between features, nor regenerates geometry on parameter change. Full-blown parametric control can be embedded into any 3D part (including imported one) using 3D constraints.
